As a class teacher, the strongest emotion in our hearts is so holy. I hope that the class will become a warm home for students, so that every child can pretend to study, live and create in the arms of love, face the sunrise like flowers, suck the showers and grow up healthily in the fertile soil of the class. Educator makarenko summed up in his long-term educational practice that a good class group is not only the object of education, but also the great power of education. It can be seen that a good and harmonious class group has strong influence, appeal and control over its members. What is a harmonious class group? The author believes that a harmonious class collective refers to the collective members who have a strong love and sense of responsibility for the class in their daily class study and life. A class group with strong cohesion is a class group that can satisfy students' desire to learn, learn and know the truth, goodness and beauty. A harmonious class group is not only reflected in the harmony between people, but also in the harmony between people and the environment. How to build a harmonious class group? The author has the following ideas. First, the first priority of harmony-giving love. Spring breeze blows away flowers and green grass, so the earth is full of vitality. The sea contains hundreds of rivers before it has broad potential. With our Andersen-like childlike innocence, green patience and icy tenderness, we can soothe children's immature and ignorant hearts ... Students, especially middle school students, are in the formative period of their psychological character. They can't stand strong winds, heavy rain and scorching sun. They need the tenderness and care of love. Mr Xia Gaizun thinks that "education without emotion and love is like a pond without water. Without water, it can't be a pond. Without emotion and love, there is no education. " It takes ten years to plant trees, but it takes a hundred years to cultivate people, so it is not easy to educate people. Love can give students confidence. Tao Xingzhi once said earnestly: "You have Watt under your pointer, Newton in your cold eyes and Edison in your ridicule", which shows the power of love. Class collectives should not only pay attention to students with prospects for further study, but should become hotbeds for all students to develop their personalities and specialties. Love is the necessary nourishment for children's healthy growth, and it also quietly nourishes the harmony of the class. Second, the necessity of harmony-create a relaxed and happy environment. In the process of class management, we always put hygiene in an important position in class work, and everything in the classroom is always in good order, creating a clean and pleasant learning environment. In the long run, everyone can abide by the rules, study hard and maintain the order of class study and life. Some people may think that this is a trivial matter and meaningless. Is it a mountain out of a molehill? However, we think that the concept of health is related to the mental outlook of a class, and it will always give students some hints. The Book of Songs says: "When I entered Lan Zhi's room, I didn't smell its fragrance for a long time; Once I entered the abalone, I didn't smell it for a long time. " It can be seen that good class spirit exerts a subtle influence on students. Therefore, in class construction, we should pay special attention to the construction of the big environment, form a correct public opinion orientation, and let students standardize their behavior under the overall drive, starting from small things and starting from bit by bit. As the saying goes, "sweep the house first, then sweep the world." Third, we need harmony-creating a cultural atmosphere. The group atmosphere is formed through the cultural atmosphere representing the group characteristics. Once formed, it will affect individuals, and a good class cultural atmosphere will make students feel happy and have a sense of accomplishment. Therefore, we fully mobilize students' active participation and jointly create class culture, so that students can experience the harmonious atmosphere of the class collective in the construction of class culture. In order to better promote the communication between teachers and students, students and students, and create a harmonious atmosphere in the class, we posted elaborate aphorisms on the walls of the classroom, such as "A drop of water will not dry up unless it flows into the sea, and a person will be full of vitality only if he is integrated into the group", "Doing things seriously can only be done right, and doing things with heart can be done well" and "Learning requires thinking, thinking and rethinking." And so on, let the ceramic students with rich spiritual civilization comfort their hearts and lead them to be positive and pursue spiritual values. We discussed with our classmates and built an alternative column of the blackboard newspaper in our class, such as the "Learning and Life" version, so that students can find the shadow of learning in their lives with their own eyes and record all the cases of learning and life. There is also a "vent center" version, which allows class members to vent their emotions and express their feelings about study and life, so that class members can fully understand, trust and help each other, so that the class collective can become a post station for each member's spiritual exchange, create a positive atmosphere for each group member's self-psychological process, and make the class a mutually supportive group. Especially the "message board", students leave messages to teachers, classmates and even classes every day. Teachers also leave messages for students, build a platform for mutual help and communication between teachers and students, and build a bridge for communication between teachers and students. For example, when students have made great progress in which course they have studied, the teacher will leave a message in this column to praise and encourage students, so that students can really feel the attention and care of the teacher, and also let the teacher know the students' situation in time from the students' messages, so as to build a harmonious group that students can trust. Fourth, the importance of building a harmonious class committee. The head teacher is full of details and sundries. We don't think the head teacher should be a nanny and do everything by himself. We must establish a class committee with the monitor as the core. The class committee is the core of class management and the backbone of class daily management and activities. The members of the class committee in our class are recommended by classmates and reviewed by teachers. The members of the class committee are trustworthy, enterprising and responsible students. Moreover, class cadres do not practice "life tenure", but listen to students' opinions at any time and make reasonable changes. This not only improves the enthusiasm of class cadres, but also gives full play to the spirit of "class teacher" of students, so that they can grow up healthily, comprehensively and harmoniously in the dual process of learning and management. In the process of class management, we require class cadres to record class logs every day, taking what happened around them as clues, expressing their true feelings as an opportunity, promoting good as the main goal and punishing evil as an auxiliary means. Before school, the recorder reads the class diary in the whole class, so that every student can pay attention to his performance in school that day, whether he is appreciated by everyone, and whether there are mistakes to be improved in class, so that some students' attitude of dismissing verbal reminders and criticisms on weekdays will be published in public once it is written in black and white, which will attract considerable attention. This has greatly enhanced the cohesion of the class to a certain extent, and played a very good role in promoting the formation of the collective psychology of building a harmonious class. The so-called "one of the arts of collectivism education is that teachers are good at translating their praise and criticism of a student into a correct collective evaluation of the student, and at the same time, they also stimulate positive domestic demand motivation." Some people say that the junior middle school class collective should be a boat that takes students to the ocean of knowledge, a solid bridge for students' personality and psychology to mature, and a nutrition station for students to become "socialized people". Then as a class teacher, a team leader, a designer and a nutritionist, they shoulder the heavy responsibility of building a harmonious class collective, leading students to sow, cultivate and harvest together.
